변수가있는 ObjectOfRoutes 클래스와 그 get set 메서드가 있고 또한 웹 서비스를 구문 분석하고 ObjectOfRoutes 개체를 arraylist (ArrayList)로 설정하고 해당 arraylist를 전달하려고하는 DirectionParser 클래스가 있습니다. 다른 활동을 내가 각 목록보기 행을 클릭하면. (asynctask있는 webservice 구문 분석하고 listview onItemClick() 함수를 실행합니다.) 그 ObjectOfRoutes Parcelable 구현하지만 시도 int 여분의 arrayList null 때 디버깅 할 때 말한다.분해 할 수있는 문제
아무도 도와 줄 수 있습니까?

나는 onItemClick() intent.putParcelableArrayList ("arrayList", loadingDirecitons.arrayList);를 전달하려고합니다. LocationViewWithVicinity 클래스에서 수신하지만 null을 반환합니다. serializable whath 구현 후 – user1563671
는 Serializable를 가진 모델 클래스를 구현합니다. 본
intent.putExtra ("배열",의 ArrayList)처럼 ArrayList를 전달할 수 직렬화
같은 클래스 ObjectsOfResults을 이다;
그리고 당신이
getIntent() getSerializableExtra ("배열")와 같은 다른 활동에 동일하게 검색 할 수 있습니다.;
조금 더 설명 할 수 있습니까? – user1563671
arraylist가 null이 아닌지 확인하십시오. 먼저 –
이 제어하는지 확인하십시오. 다른 활동에 전달할 값이 있는지 확인하십시오. – user1563671
귀하의 질문을 정확하게 이해하는 데 어려움이 있습니다. 그러나 test project에있는 활동간에 ArrayList를 전달하는 예를 찾을 수 있습니다.
